I actually have a piece of original art done by Cardy. A cover to a DC horror comic, which I bought way back in the late-1970’s for about ten bucks.
I didn’t care much for “Teen Titans.” But Cardy was a good artist. Some of his art in the early issues of “Bat Lash” are absolutely beautiful.
Concur - I have many of his issues including the TT and Bat Lash, some of the Aquaman are much more detailed than other artists of the day (with exception of Neal Adams). I envy you your original.
